Can I have two "funded" Roth IRA accounts? I know that I am subject to yearly contribution limit ($4k I believe last time I checked).. can I put $2k in one, $2k in another?

Reason for this is because I want to open a Roth IRA account with Janus in order to have 1/2 of my money invested in one of their mutual funds (my wife is a longtime Janus mutual fund investor and we both love the Janus Overseas fund), and another 1/2 in something like TradeKing or other discount brokerage where I will do more hands-on investing.

So, hopefully I can have two Roth IRA accounts for this purpose, or is it against the code?
